• Use the no seq sequence-number command syntax if you know the filter’s
sequence number
• Use the no deny udp {source address mask | any | host ipv6-
address} {destination address | any | host ipv6-address}
command
Parameters
source address Enter the IPv6 address of the network or host from which the
packets were sent in the x:x:x:x::x format followed by the
prefix length in the /x format. The range is /0 to /128. The ::
notation specifies successive hexadecimal fields of zero.
mask Enter a network mask in /prefix format (/x).
any Enter the keyword any to specify that all routes are subject

host ipv6-
address
Enter the keyword host followed by the IPv6 address of the
